Galatians 2:7-9

Instead, they saw that God had given me the responsibility of preaching the gospel to the Gentiles, just as he had given Peter the responsibility of preaching to the Jews. For the same God who worked through Peter as the apostle to the Jews also worked through me as the apostle to the Gentiles. In fact, James, Peter, and John, who were known as pillars of the church, recognized the gift God had given me, and they accepted Barnabas and me as their co-workers. They encouraged us to keep preaching to the Gentiles, while they continued their work with the Jews.
